| 摘 要： | 利用场发射扫描电子显微镜(FESEM)研究了纤维状二氧化硅纳米球(KCC-1)的形貌,探讨了样品前处理方法、加速电压、工作距离、发射电流、减速模式对其FESEM图像的影响规律。结果表明,影响FESEM成像的因素较多,其中样品前处理方法、工作距离和加速电压是影响图片质量的主要因素;选择乙醇为溶剂、硅片为基底、较小的工作距离、较低的加速电压、高发射电流、减速观察模式的优化观测条件可获得理想的FESEM图像。

| Abstract: | The morphology of fibrous silica nanospheres (KCC-1) prepared by hydrothermal synthesis was studied by field emission scanning electron microscopy (FESEM).The effects of different conditions on its FESEM image were investigated,such as sample preparation method,accelerating voltage,working distance,emission current,deceleration mode.The results show that factors affect the quality of FESEM .The sample pretreatment method,working distance synthetically and acceleration voltage are the main factors.Choosing of ethanol as solvent and,silicon as the base,using the shorter working distance,low accelerated voltage,high emission current,and deceleration observation mode can obtain the ideal FESEM image. |

| Keywords: | Field emission scanning electron microscopy Sample preparation Low accelerating voltage Deceleration mode |
